#include<stdio.h>

int conv(int F);

int main()
{
int F;

for(F=0; F<300; F=F+20);
{
scanf("%d",&F);
printf("%d, ",F);
printf("%d\n",conv(F));
}
}

int conv(int F)
{
return (F-32)*(5/9);
}

I am new to programming, and have been set a task to print a table of Fahrenheit values and equivalent Celsius values. This code I have written doesn't seem to work and I'm not sure why?

Because you overwrite value of F when you read input (scanf function). And remove that semicolon after for. Also, in your converting function you have to multiply by floating point number because integer division of 5 / 9 is 0.

Thank you--it's been driving me mad! I have actually got it spitting out values now, but every value after the comma is 0? I got rid of the scanf (don't think I needed it) and the semicolon after for, I think there's something wrong with my 'conv' function but I'm not sure what

ahhh got it... thanks very much, it would have driven me mad
